SHUTTLE-FEELER THREAD CUTTER Ann CLAMP.

Application filed December 3, 1925. Serial No. 72,891.

To all whom it may concern:

Be it known that I, ELIAS E). Moore), a citizen of the United States, residing at Lynchburg, in thecounty of Campbell and State of Virginia, have inventedan Improvement in Shuttle-Feeler Thread Cutters and Clamps, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to shuttle feeler thread cutters and clamps whereby the end of the out-going filling is cut and removed from the danger zone of being carried into box, the parter and clamp act to cut and clamp the filling end, and then move the filling end leading from the clothselvage frontwardly so that it may be later brought into the action ofthe temple thread cutter.

Feeler thread cutters and clamps as heretofore made have in most instances comprised a movable and a stationary parter mounted on the shuttle feeler and a movable and stationary clamp, and the parts have been held to the shuttle feeler by a bolt, between the head of which and the outside member of the assembled parts, a spring washer has been applied for holding the elements of the thread parter and clamp in laterally cooperative relation.

One-of the objects of the present invention is to provide a shuttle feeler thread parter and clamp wherein one of the members shall be constituted asa laterally acting spring interposed between the head "of the usual.

bolt on the shuttle feeler and the adjacent elements of the thread parter and clamp,-

so that it performs the dual function of a clamp member and a spring washer. This simplifies the construction and avoids the multiplicity of parts that have heretofore been incident to shuttle feeler thread parters and clamps.

In accordance with the present invention,

the spent filling end adjacent the inner portion of the shuttle box is cut by the thread parter and is clamped in two places, con stit-uting what may be well termed a double grip shuttle feeler thread parter and clamp. The clamping elements are preferably formed of afixed clamping member and a 00 movable clamping member mounted for movement with the movable parting member, and one of the clamping members is constitutedas a spring plate to act as a clamping member and also as a spring Washer to hold the parts of the parter and clamp in lateral cooperation.

In the drawings:

Fig.1 is a perspective view of portions of a loom provided with a shuttle feeler having the present invention applied thereto;

Fig. 2 is an enlarged plan view of the end of the shuttle feeler and parts constituting the" present invention;

' feeler may be as desired, but is herein shown as comprising an arm 1 having a hub 2 which is pivotally' mounted upon a bolt 3 carried by a bracket 4 secured to the loom frame. The shuttle feeler 1 has its free end portion provided with the jaws 5 and 6, which maybe as usual, and extending laterally from the rear end portion of the shuttle feeler, is a stud or bolt 7 on which some of the parts of the thread parter and clamp are mounted, as will more fully appear.

The lay 8 may be of usual construction and is herein shown as provided with the transverse recess 9 into which the rear end portion of the shuttle feeler 1 may pass when the shuttle feeler is moved to rearward feeling position. The lay 8 carries the usual shuttle box 10 for the reception of the shuttle 11, and it will be seen from Fig. 1 that the filling a extends from the shuttle or shuttle box opposite the shuttle feeler, so that if the latter be moved into its rearward shuttle feeling position, the thread"awvill-bepositioned for the action of the thread -parter and clamp.

'lhemeans for moving the'shuttle' t'eeler:

into its rearwardfeeling position is-not of the essence of the present invention and the full train of mechanism. for'eitecting:

this purpose is not herein illustrated and may be of any usual construction: Inthe present instance the jaws 12 and 13 which are actuated on call for replenishment of filling, contain between themthe pin 14 ex tending from the shuttle fe'eler, so thaton call for replenishment'of filling, the shuttle feeler is'moved to its :t'ul'lshuttle-feeling po sition, .as is well understood by those familiar with looms.

The shuttle 'leeler has secured: thereto afixed "parting blade orcutter 15, and mounted upon the studor pivotpin"? is theco operating movable parteror cutter 16, ha m ing the tail-piece l'lwlrich is adapted to -be" struck by a part carried bythe' lay-'as'the lay moves frontward .or as-rthe'shuttle feeler'inoves rearwardlyin order to actuate the movable parter to part=the thread; The

action of the fixed and*movable'par ers is not unlike that nowalready in common use.

Mounted upon the shuttlefeeler is the" fixed clamping member 18fwlrichi may be securedto the: shuttle *feeler' in any appropriate way, but is herein shown asmountedupon the stud or pivot pin 7,'and: its front end "portion is bifurcated, as 'at' 19,- towreceive" a pin 20 extending through? .aho'le -21 in the movable "parter: Thism-anner-of assembling the-fixed and movablepartersrand the fixed clamping member is not-new exceptin so far as these parts are coordinated with the other-member of the parter, as twillnow be described;

In shuttle feler thread cutters and parters of the type described, it'is usual to providea' springof some sort between-*thehead of the bolt" or stud 7 and the sideof the exterior member o'f'the parter and clamp, t hold the Parts propercollateml itig for the performance. of their respectivefunctions. Inthe present'instance,however,

the spring-washer is dispensed with; and the movableclamping member; herein indicated as the plate 22 is= pivotally mo-unted upon the. stud or bolt? and is hollowed or'dished, as indicatedmoreclearly in" Figs. .2, 4 and 5. The dishedformation o'l' themovableparter member 22. gives to the partingmember a flexibility or-resiliency, so that:

when interposedbetween the hea-dgot the stud or bolt? and the adjacent-membersof the thread parter and clamp, the *mov-ableclamping member 22 serves the dual pur pose of a clamp to clamp the-thread and a spring washerto' hold'the'elenientsof the parter and clamp into-laterally associated relation.

The'movable-memberi22 of the clamp is given its movement 1 with the movable mem ber of the thread partor and consequently the present invention contemplates that the,

movable member 22. of. the: thread clamp shall be connected for movment with the niov-ablesthreadparterz vAs shown in the present instance of the invention, the dished plate- '22hasits frontward end portion recessed as at 23, forming shouldered portions 2% ant 25 which rest upon correspond-: ing portions of the tail piece 110-tithe: movable thread parter and serve to connect the. movable dish ed clamping memberr 22 with l the movable 'p-arter.

The movable clainping member. 22: has the central-'o pemngfltig as indicated in Figs: 3,1. 4 I and 5,- through 1 which the stud or bolt17 1 passes; and the movable: clamping member 22 is thus interposed 1 between the head of the-stud or-bo lt 7 and the asembled elements 01 the parterand: clamp adjacent thereto; so that" the edge: portionsQT ot-thewdished;

and bytighteningthestud or: bolt 7 or course the spring'action ofthe dished plate: or member 'QEZ'may be made; more or; less. energetic 1n holding the parts of thetthread part'er and clampin their laterail operativeposition.-

The-fiexibility of the member. 22Lofithe clamp is augmented byproviding thedished plate constitutingsthe' movable member 2213 of-the clam-p with A a series-.-.oit\ openingsfltv" which maybe disposed abouti'he surfaceiof thedished-plate. The number orl such open-r ingsof coursemay vary or they might in: some casesbe dispensed with altogetherlprovided the plate itself isgiven: sufficient late.

good" practical I form of the present inven" tlon, 1t -Wlll be apparent that when the shuttle fe'eler thread part-er and clamp are in their rearward operating position illltbalez:

double grip type and the twoclanrpin-g" meinb'ersare relatively movable, .one being constituted as a spring. plate-interpcsed between the head of the stud or bolt projecting from the shuttle feeler andithe elements of the parter and clamp, to act as a spring washer in holding the parts in lateral 00-.

operating relation and as a clamp for the parted thread.

"When the shuttle feeler thread parter and clamp are moved to their rearward parting position on call for replenishment, the jaws of the parter and clamp are opened, as indicated in Fig. 1, and such opening movement is efiected by the usual trip 29 mounted upon the upstanding arm 30 secured to the loom frame or bracket supported thereby. The trip 29 cooperates with the pin 31 to open the jaws of the parter and clamp as it moves to rearward position, but as these parts form no essential part of the present invention and are now well understood, no further description or illustration appears necessary.
